“Fun slipping into the doctor's role”—The relationship between sonoanatomy teaching and professional identity formation before and during the Covid-19 pandemic

The various psychological dimensions of professional identity formation (PIF) are an important aspect of the study course for undergraduate medical students. Anatomical learning environments have been repeatedly shown to play a critical role in forming such an identity; however, relevance of PIF during sonoanatomical training remains underexplored. At the end of their basic anatomy studies, third-semester medical students took part in a four-day block course on anatomy and imaging. Anatomical content was revised in small groups using peer teaching and imaging methods, including one hour of hands-on sonoanatomy sessions each day. On-site sonoanatomy was identified as an excellent format to support students' transition from the pre-clinical to clinical phase as medical experts-to-be. Students enjoyed practical exercises and the clinical input, which increased their interest in the medical profession and their academic studies. This study further examined the effects of the transition into an online-only format, necessitated by the current Covid-19 pandemic. A comparison was made between the quantitative and qualitative evaluation data, and the written results of examinations of several on-site (n = 1096, mean age = 22.4 years ± 2.18), and online-only cohorts (n = 230, mean age = 22.6 years ± 2.21). The online-only transition led to a reduction of all PIF-related variables measured, losing identity-related variables, increasing students' stress levels, and reducing their long-term academic performance. Together, this study demonstrates presence of PIF in undergraduate sonoanatomy teaching, and cautions against the uncritical online-only substitution of hands-on learning environments.     

Quality Impact on Diagnostic Blood Specimen Collection Using a New Device to Relieve Venipuncture Pain

A new device called Buzzy^® has been recently presented that combines a cooling ice pack and a vibrating motor in order to relieve the venipuncture pain. The aim of this study was to evaluate the impact of Buzzy^® use during diagnostic blood specimen collection by venipuncture for routine immunochemistry tests. Blood was collected from 100 volunteers by a single, expert phlebotomist. A vein was located on the left forearm without applying tourniquet, in order to prevent any interference from venous stasis, and blood samples were collected using a 20-G straight needle directly into 5 mL vacuum tubes with clot activator and gel separator. In sequence, external cold and vibration by Buzzy^® was applied on the right forearm—5 cm above the chosen puncture site—for 1 min before venipuncture and continued until the end of the same procedure already done in the left forearm. The panel of tests included the following: glucose, total cholesterol, HDL-cholesterol, triglycerides, total protein, albumin, c-reactive protein, urea, creatinine, uric acid, alkaline phosphatase, amylase, AST, ALT, g-glutamyltransferase, lactate dehydrogenase, creatine kinase, total bilirubin, phosphorus, calcium, magnesium, iron, sodium, potassium, chloride, lipase, cortisol, insulin, thyroid-stimulating hormone, total triiodothyronine, free triiodothyronine, total thyroxine, free thyroxine and haemolysis index. Clinically significant differences between samples were found only for: total protein, albumin and transferrin. The Buzzy^® can be used during diagnostic blood specimens collection by venipuncture for the majority of the routine immunochemistry tests. We only suggest avoiding this device during blood collection when protein, albumin and transferrin determinations should be performed.     

Developmental Improvements and Persisting Difficulties in Children’s Metacognitive Monitoring and Control Skills: Cross-Sectional and Longitudinal Perspectives

This study investigated age-dependent improvements of monitoring and control in 7/8- and 9/10-year-old children. We addressed prospective (judgments of learning and restudy selections) and retrospective metacognitive skills (confidence judgments and withdrawal of answers). Children (N = 305) completed a paired-associate learning task twice, with a 1-year delay. Results revealed improvements in retrospective, but not in prospective monitoring and control. Furthermore, control remained suboptimal, seemingly a consequence of overoptimistic monitoring. Both age groups showed stronger monitoring-based control at the second compared to the first assessment. The comparison with a cross-sectional sample (N = 144) revealed that improvements in retrospective monitoring can be mainly attributed to naturally occurring development, whereas retrospective control seemed to improve due to increased task familiarity.     

Transition to child care: associations with infant-mother attachment, infant negative emotion, and cortisol elevations

Seventy 15-month-old infants were studied at home before starting child care, during adaptation (mothers present) and separation (first 9 days without mothers) phases, and 5 months later. Security of infant-mother attachment was assessed before and 3 months after child care began. In the separation phase, salivary cortisol rose over the first 60 min following the mothers' departures to levels that were 75% to 100% higher than at home. Compared with insecure infants, secure infants had markedly lower cortisol levels during the adaptation phase and higher fuss and cry levels during the separation phase, and their fuss and cry levels were significantly correlated with their cortisol levels. Attachments remained secure or became secure if mothers spent more days adapting their children to child care.     

Making connections among multiple visual representations: how do sense-making skills and perceptual fluency relate to learning of chemistry knowledge?

To learn content knowledge in science, technology, engineering, and math domains, students need to make connections among visual representations. This article considers two kinds of connection-making skills: (1) sense-making skills that allow students to verbally explain mappings among representations and (2) perceptual fluency in connection making that allows students to fast and effortlessly use perceptual features to make connections among representations. These different connection-making skills are acquired via different types of learning processes. Therefore, they require different types of instructional support: sense-making activities and fluency-building activities. Because separate lines of research have focused either on sense-making skills or on perceptual fluency, we know little about how these connection-making skills interact when students learn domain knowledge. This article describes two experiments that address this question in the context of undergraduate chemistry learning. In Experiment 1, 95 students were randomly assigned to four conditions that varied whether or not students received sense-making activities and fluency-building activities. In Experiment 2, 101 students were randomly assigned to five conditions that varied whether or not and in which sequence students received sense-making and fluency-building activities. Results show advantages for sense-making and fluency-building activities compared to the control condition only for students with high prior chemistry knowledge. These findings provide new insights into potential boundary conditions for the effectiveness of different types of instructional activities that support students in making connections among multiple visual representations.

Special curricular themes for library education in Nigeria

The Nigerian society has cultural and social differences from those of people in developed countries from which educational programmes and practices have been borrowed. The differences are reflected in the peculiarities in the majority of Nigerian citizens’ need for educational and informational services in libraries. In responding to these peculiar needs of a people whose majority has had no tradition of using books, the librarian who administers their needs may require education and training which must differ in content from the conventional library programmes as currently borrowed from developed countries.

Core courses for the training of librarians who are expected to provide information which may not be recorded in print form, have been suggested for preparing these librarians for the kind of service that would sustain the interest and appreciation of their clientele in the use of libraries. The selected courses, based on the culture and structure of the people, will involve the production of literacy resources, information gathering and dissemination for non-literates, book publishing to conform with local demands and public relations activities which would ensure the social relevance of the library school programmes to the needs of the society.
